SILVERWARE-DRYING MACHINE.

Application filed January 14, 1922. Serial No. 529,233.

To all whom it may concern:

Be it known that I, EZRA S. EATON, a citizen of the United States, residing at Newton, in the county of Middlesex, in the 5 State of Massachusetts, have inventeda certain new and useful Improvement in Silverware-Drying Machines, of which the following is a specification, reference being had to the accompanying drawings.

Th immediate object of my invention is to provide a simple and effective means for drying wet silverware and dishes, also to hold the silverware in a plurality of containers or trays so that a large quantity maybe handled simultaneously. A further object of my invention is to continually circulate heated air over the surfaces to be dried in one direction thus by forced evaporation increasing the drying capacity of the drier. A further objectof my invention is to circulate the heated airat a high velocity Fig. 5 is a part sectional view showing the door open.

Fig. 6 is a front elevation showing the drier and Washer combined.

Fig. 7 is a longitudinal sectional view showing the drier and washer combined.

Referring to the drawings in detail the numeral 10 is the casing of the drier and 11 is the door which is hinged to the front of the casing at 12 and swings downward to a level position resting on the edge 13 T. The trays T being perforated on the sides.

The blower B is attached to the drier casing 10, the suctionpipe 15 is at the top and the discharge pipe 16 is at the bottom of said casing. The heating unit is located within the casing 10 and under the partition 14 and is supplied with steam or any heating medium through theconnections 17.

In operation the blower B is driven by of the partition 14 which supports the trays the motor M, the air is forced over the heating unit G up through the perforated trays T and the suction of the blower B creates a partial vacuum-in the suction pipe 15 thus drawing the air from the material in the trays T and increasing the evaporating power of the heated air. From the description and arrows shown in Fig. 2 it can readily be seen that the air is circulated in a closed circuit, and that the air can be circulated at a high velocity. The trays T of material to be dried are put in and removed from the drier through the door 11. The door 11 is provided with a fastener which when unfastened permits the door to swing down'and rest on the edge of the partition 14, and this completely closes the passage through which the air passes from the heating unit, this preventing escapement or lowering of the temperature of air under the door 11 as shown in Figures 4 and 5. However, in removing the trays T over the door '11, a portion of the partially saturated air is withdrawn from above the partition 14, and relatively dry air enters. WVhen the door is again raised, this completes the continuouspassage around the partition 14, and thus re-establishes the circulation of air. As the newly supplied air becomes heated andexpanded, a safety valve 10 permits more of the partly saturated air to escape.

The trays T are passed from the washer W to the drier through the door 18 over the guides 19 to the drier through the door 20 in the side of the casing 10 when used in combination with the washer as shown in Figures 6 and7.

Having thus described my invention I claim:

1. The combination of a casing, a substantially horizontal partition therein and spaced from tWo ends of the casing so as to provide a continuous air-passage, a blower in said air-passage, a heating unit in the air-passage, and a door hinged to the casing and swingable from a position for closing the casing to a position for providing an outlet and at the same time closing the airpassage, and means to be supported on said partition and to hold material to be dried, said means being adapted to be Withdrawn through said outlet.

2. The structure defined by claim 1, the

hinge of said door being substantially in the plane of said partition, so that the deer "forms a horizontal continuation of the partition and an additional support for the last 5 said means when the air-passage is closed by the door.

3. The structure defined by claim 1, said casing being provided with an inlet and with means at its inlet for guiding said meterial-holding means from a Washer when the latter has its outlet in registration with the inlet, the said guiding means being substantially level with said partition.

EZRA S. EATON.
